Build an UNSIGNED swap transaction on X1 at the best price across XDEX and APEX AMM — direct, or two hops through XNT or APEX in ONE transaction, simulated against your wallet before it is returned. Returns base64 you sign with your own key and broadcast yourself; this server never holds your keys and never signs for you. Use mint addresses, or the string "native" for XNT. APEX mint is Du6Z596DwGnfUcMSyRHSBQzNybiQKu8GESVfruEv9Jqr. Check priceImpact before signing — thin pools move hard. Free; you pay only the network fee.
